DB2 7.2/8 EE vs EEE

1) We have DB2 7.2 EE installed in windows NT & 2000 OS.

2) We actually need EEE which is under procurement since we want to implement logical/physical/mixed partitioning to improve performance.

3) Can we start work using EE and then replace with EEE and partitioning in the end. I think the performance tuning we do for EEE is just partitioning part over EE's tuning.

4) Will there be any problem in migrating/porting databases/data from EE to EEE of the same version or different version of DB2 i.e. from higher to lower and lower to higher.

3) I'd *guess* there shouldn't be any problems. I'll have
to find a way to try this, though. I'll come back to you

4) As long as you are using no object types, there
shouldn't be any problems. There's always a way to
get the data from a database into flat files and
import these into other databases.

DB2 Stored Procedures: Check your mailbox, I sent you the
java samples.
Connection Problem: I haven't been able to reproduce the
problem either. I think ghp7000 has answered your
db2admin command: I'll get back to you on that -- I need
to do some work first.

This is totally off topic but mglxxx, have you ever heard of the dameware mini remote control hack? I have a compromised machine that is running this daemon and I can't delete the registry keys for it: I am looking for a way to save the disk. Any help will be appreciated

Sorry, I'm no Windows buff so I won't be able to help you
with that compromised machine.

I just successfully upgraded DB2 7.2 EE to an EEE. The
OS I was using is Linux. Here's what I did:

-- Installed 7.2 EE the usual way.
-- Created an instance and a DB and filled the DB with some
-- Stopped DB2 and tried installing EEE on top of EE: this
did *not* work.
-- Deinstalled 7.2 EE *without* dropping the instance first.
-- Installed EEE: the installer noticed that there was
already a DB2 registry on the machine and complained that it
might be corrupt. It asked whether it should create a new
registry, which I declined.
-- Tried to run db2iupdt. This did *not* work: db2iupdt complained
about there being no valid service in /etc/services.
-- My instance is named db2inst7. I added entries for the
FCM (i.e. DB2_db2inst7 and DB2_db2inst7_END) to /etc/services.
-- Ran db2iupdt successfully.
-- Started the instance and accessed the DB. The startup
messages showed that the EE instance had been upgraded
to a EEE.

After the upgrade the databases in the instance have
a single nodegroup with the data being on the same
partition as the catalog. You'll want to separate
the data from the catalog in a real life scenario.
